Could it be the Vehicle Speed Sensor?
So I attempted to install a stereo in my car today. I purchased the Scosche wiring harness, which I used to connect between the factory harness and stereo harness. That was straightforward. When I turned my car on, the stereo turned on fine, but when I put it in reverse, the car jolted. When I put it in drive, it jolted again. Weird stuff. I figured I should drive a little and see what happens...it's not good. Here's my list of symptoms;
1) Car stays in 2nd or 3rd gear (can't tell cuz the speedometer doesn't work)
2) Speedometer doesn't work
3) Gas gauge literally goes up when I cruise and down when I press the gas
4) Service engine soon light is on
5) SRS (airbag) light is on
I disconnected my negative terminal for 40 mintues and reconnected.
I pulled out my ECU. I checked the fuses in the engine bay and the driver's side fuse box area
I put the old radio back in my car
I visually inspected the wires behind the center console and driver's side fuse area. Everything 'looks' fine. I didn't hear any noises or have any weird odors.
From reading online, it sounds like it may be the vehicle speed sensor causing the issue. Can any of you gurus shed some light on the issue? I really don't want to go to the dealership with my tail between my legs if I can help it.
thanks.
